THOMAS JAMES RAYNER, OF LONDON, ENGLAND.

SURFACE CONDENSER.

SPECIFICATION forming part of Letters Patent No. 468,048, dated February 2, 1892.

Application led August 11, 1891. Serial No. 402,386. (No model.) Patented in England April Z1, 1888, No. 5,972.

To all whom it may conceive:

Be itknown that I, THoMAs JAMES RAYNER, a citizen of England, residing at No. 777 Oommercial Road, in the county of London, England, have invented a new and useful Surface Condenser, (for which I have obtained a patent in Great Britain, dated April 2l, 1888, No. 5,972,) of which the following is a speciiication.

My invention relates to a construction of surface condenser consisting of a number of tubes coiled in volute form and connected together Within a casing supplied with water surrounding the tubes, so that steam passed through these coils becomes condensed, heating the surrounding water for use as boilerfeed or generating vapor from it to be condensed as distilled water.

Figure l of the accompanying drawings is a vertical section, and Fig. 2 is a sectional plan on the line 2 2 of Fig. l, of a surface condenser according to my invention, arranged to operate for distillation of sea-water.

A is a casing, preferably of cylindrical form and provided with tightly-closing covers at top and bottom and having on its top cover a safety-valve B, a pressure-gage C, and a stopvalve D, The lower part of the casing is occupied by a number of pipes (preferably of thin copper) E E2 E3, tbc., coiled in volute form, all these coils being attached to a cover F, which is bolted to flanges at one side of the casing. By unscrewing the bolts the cover F, with the coils attached to it, can be removed from the casing, so that the coils can be cleaned or repaired when necessary. In the cover F, at one side of it, there are formed a number of cavities f'f2f2f4, according to the number of coils E E2, dec. The uppermost cavity f communicates with a passage from an inlet G for steam. The lowest cavity f* communicates with a similar passage to an outlet for water of condensation. One end of the uppermost coil E is jointed to f and one end of the lowest coil Ei is jointed to f4. Of the other coils the ends of E2 and E3 are both jointed to f2 and the ends of E4 and E5 are both jointed to f3. The inner ends of the coils are jointed to junction-cavities K receiving the ends of E and E2, K2 receiving the ends of E3 and E4, Ks receiving the ends of and E6.

Thus steam entering from G to f passes inward through the uppermost coil E to K', thence outward through the coil E2 to f2, thence inward through E3 to K2, and so on, taking a zigzag course inward through the one coil and outward through the next coil below to the last cavity f". Obviously there might be a greater or less number of pairs of coils, the connecting-cavities and K being arranged accordingly.

At the side of the casing A is iixed a feedcistern H, furnish ed with a ball-cock or iioatvalve, by whichthe water to be distilled is admitted to maintain its level within the casing a little above the uppermost coil E. Several perforated plates I and baille-plates J may be arranged, as shown, in the upper part of the casing to prevent water from priming over with the vapor generated. This vapor passes away by the valve D to any suitable condenser, the resulting water being used either for drink or for feeding boilers with fresh water at sea. In the latter case the vapor generated may pass to the main condenser, so that the evaporation goes on under greatly-reduced pressure.

lVhen the apparatus is used as a condenser or feed-Water heater, the casing need not extend much above the uppermost coil, cold Water being supplied to it near its bottom and the heated water being conducted away from its top.

Having thus described the nature of this invention and the best means I know for carrying the same into practical effect, I claim- 1. A surface condenser comprising a series of pipes, each pipe of the series coiled in vo lute form and the whole arranged one above the other to form a stack of volute coils one above the other, communicating with one another for the passage of steam from one to the other from one end of the stack to the other consecutively through each coil of the series, substantial] y as and for the purposes set forth.

2. A surface condenser comprising a series of volute coils of pipe arranged one above the other and communicating with one another, a chamber inclosing said volute coils, and a removable cover having the series of volute coils connected thereto, substantially as and for the purposes set forth.

3. A surface condenser comprising a series of volute coils arranged one above the other,

IOS

junction-cavities connecting the inner ends of pairs of the coils for the passage of steam from one volute coil to the other of the pair, and j unetion-cavities connecting the outer end of one coil with the outer end of a coil adjacent thereto, substantially as and for the purposes set forth.

4. A surface condenser Comprising a series of volute coils of pipes communicating with one another for the passage of steam from one end of the stack to the other consecutively through each coil of the series and arranged one above the other,a chamber inolosing said coils, a feed-cistern communicating with said inclosing chamber and provided with an automatically-acting valve to maintain a level of Water in said chamber, and an outlet for the Water of condensation from said volute coils of pipes, substantially as and for the purposes set forth.

In testimony whereof I have signed my naine to this specification, in the presence of two subscribing Witnesses, this 31st day of July, A. D. 1891.
